Description
Technical field
The present invention relates to a kind of adjustable length, telescopic support in general, as pillar or strut that they are for example used as concrete mould panel element in civil engineering.In particular, the present invention relates to a kind of for making the releasably interconnective G shape hook of two brace sections of so telescopic structure stand.In addition, the present invention relates to a kind of telescopic structure stand, the brace sections of this structure stand can releasably interconnect by G shape hook according to the present invention.
Background technology
Telescopic support, as they are being used as the pillar or strut of concrete mould panel element in field of civil engineering, has the inner tube of an outer tube and a Telescopic movable in this outer tube conventionally.A common so-called G shape hook with circular cross section is for two pipes are releasably interconnected, and this G shape hook extends through and is configured in through hole in described two pipes and that mutually align.In this case, conventionally select as follows the form of G shape hook, that is, this G shape hook can be fixed on telescopic support anti-sliply, and this clip around described support by G shape hook completes.At this, such G shape hook is configured to member single type or monomer by round steel by this round steel being carried out to deformation processing conventionally.Because each support need to bear until the load of 4 tons or more, so must determine very modestly the size of the power delivery areas between two pipes and the particularly size of G shape hook, this is because whole load is delivered to outer tube from the inner tube of support by it.
In this size is determined, be often that conclusive size is determined criterion along the hole wall stress of the through hole of two pipes, this makes the diameter of G shape hook all must be greater than definitely in all cases the required diameter of lateral force ability to bear.Because G shape hook is owing between inner tube and outer tube being not inappreciable gap and Bending strain in addition, so the size of G shape hook determines to be conclusive equally to bending strain meeting in addition, this diameter that makes again G shape hook is selected in order to realize the large as far as possible moment of resistance to be greater than lateral force and to shift required diameter.G shape hook also has identical cross section conventionally in its whole length, although this large cross section is only necessary in the region of outer tube diameter.
Summary of the invention
Because the G shape hook of traditional jack column is crossed and is determined greatly size in view of its lateral force ability to bear in all cases thus, produce thus unnecessary weight and unnecessary expense occurs, so the object of the invention is, at least one solution is provided, utilizes this solution can reduce unnecessary weight and consequential expense.
According to a first aspect of the invention, therefore provide a kind of for the releasably G shape hook of interconnective, the feature with claim 1 of two brace sections making telescopic structure stand in order to achieve this end.
G shape hook according to the present invention comprises that one for making two interconnective pins of brace sections, and a clip, and pin lands and is fixed on support via this clip energy anticreep.Specify now according to the present invention: pin and clip are two different parts, these parts are first as different or independent assembly existence, first these assemblies are bonded into the member of a combination in the scope of manufacturing G shape hook, according to G shape hook of the present invention.Particularly, during manufacturing G shape hook, pin and clip with the relative rotation (drehstarr) interconnect, and this preferably can complete by interference fit connection, the sealed connection of shape, melting welding connection and/or brazing.
Because first pin and clip exist as independent parts thus, only completely distinguishingly determine the size of pin so can determine criterion in view of conclusive size.Therefore the regulation according to the present invention: pin has power and imports section and shift section with the power of this power importing section diametrically contraposition, described power importing section has the surface of at least local buckling, not or have at least one curvature, this curvature is not less than power and imports the curvature of the curved surface of section on the surface that described power shifts section.
Can not counterrotatingly be connected between the clip by G shape hook according to the present invention and pin, clip can be configured to open hook and can not impair realized by clip anti-slip.Due to can not counterrotatingly be connected between pin and clip, pin is drawn out not clip deflection relatively afterwards from the through hole of structure stand at this pin so in other words.Even if in this released state of G shape hook, the spacing between the free end of pin and the free end of clip also remains unchanged thus, this spacing determined as follows, that is, G shape hook can not leave from its corresponding support fixed thereon.
The power of mentioning imports section and has the surface of at least local buckling, also can be understood as so in this respect substantially smooth power and import section, it is only rounded in the transitional region of the longitudinal side to pin or be chamfered (gefast) that this power imports section.So for example quadrangular section steel also can be with acting on according to the pin of G shape hook of the present invention, this quadrangular section steel is only rounded along its seamed edge, with prevent in the region of adjoining members, particularly the undesirable stress in the region of the hole wall of stand tube is concentrated.Therefore the power by least local buckling imports section and can guarantee to be distributed on large area via the power of pin transmission, can the bore hole pressure in the region of the through hole of the inner tube of telescopic structure stand be remained on to little state in desired mode thus.
On the other hand, as hereinafter also by further setting forth, particularly when the power that need transmit via pin is not directly, and should indirectly import in brace sections via a counter nut time, power shift the conduct of section smooth or only slight curving surperficial structure be proved to be useful.Because this counter nut has smooth end side surface equally, the power of pin is transmitted section and is placed in this end side surface, thus by power shift the smooth of section or only slight curving surface not only realize the reduction of the stress between pin and counter nut.Or rather, by power shift the smooth of section or at least only slight curving surface also guarantee that pin can not reverse, this can cause " weak axle " bending around it of this pin in undesirable mode no person.In other words, shift by power section smooth constitution realization substantially anti-torsion or self centering, can guarantee that thus pin is all the time along desired direction load-bearing.
Make according to G shape hook of the present invention and be particularly proved to be in the following areas thus useful by two different, independent parts pins and clip,, in view of conclusive size determines that criterion is such as bending force ability to bear and/or lateral force ability to bear and hole wall stress, pin completely distinguishingly can be determined to its size and manufactured this pin as extraordinary section bar, and clip can be made lighter member by easy standard sections, in this way finally not only can weight reduction, and particularly can also cost saving.But make G shape hook according to the present invention and be also proved to be in the following areas useful by two different, independent parts, that is, due to multi-piece type structure, pin can be made up of the steel of different materials, particularly different qualities from clip.Therefore the steel that for example pin can be S355 by quality is made, and can be the steel that clip using character is lower, cost saving again in this way.
A kind of G shape hook of two-piece type is provided first according to the present invention thus, part pin and the clip of this G shape hook can not interconnect with the relative rotation, thus due to following true reason, , the pin that only has the power between each brace sections of telescopic structure stand of being responsible for to shift can become solid extraordinary section bar by the steel construction that for example quality is S355, for example, as forging, rolling section bar or foundry goods, and only can use more easy as the clip of anti-slip device, more cost effective standard sections, therefore can the gross weight of G shape hook and manufacturing cost be remained on to little state in the mode of addressing before.In addition, compared with traditional G shape hook, have less cross sectional area according to the clip of G shape hook of the present invention, this makes the clip can be by cold forming, and the clip of traditional G shape hook is because the reason of its larger cross sectional area in all cases must be by hot forming.Can further reduce manufacturing cost based on cold forming thus.
According to a further aspect in the invention, object of the present invention also by one with an outer tube and one in this outer tube movably the telescopic structure stand of inner tube be achieved, wherein, in order to make two pipes releasably interconnect and use according to G shape hook of the present invention, this G shape hook extends through and is configured in through hole in described two pipes and that mutually align.
Now hereinafter useful embodiment of the present invention is set forth; In addition, other useful embodiment is obtained by dependent claims, brief description of the drawings and accompanying drawing.
Hereinafter also be applicable in the corresponding way each not specifically mentioned content with reference to the feature of setting forth according to G shape hook of the present invention and structure stand according to the present invention.For example can be converted in the corresponding way on telescopic structure stand or its G shape hook in the feature of setting forth aspect pin according to the present invention.
Specify according to a kind of embodiment like this: pin have the first end that freely stretches out and with the opposed fixing the second end of this first end, in the region of this second end, described pin is so connected with clip, makes the end face on its second end of this pin outside exposed as shock surface.At this, particularly the power of pin imports section and power and shifts section and can interconnect via a transition zone, and clip preferably vertically stretches out and then extends abreast with pin towards the direction of the first end freely of this clip is at least local from this transition zone.Be transferred in clip pin single type in traditional G shape hook, unlike this, on its second end, there is an end face defining according to the pin of G shape hook of the present invention, by this end face, pin for example applies in the through hole that hammering can be driven into structure stand on the end face using hammer in the situation that by utilizing the pin that hammer referring to.
In order can pin and the clip of G shape hook according to the present invention to be interconnected with simple method, specify according to another kind of embodiment: in the region of the second end of pin, be configured with an opening in transition zone, the second end of clip is fixed in this opening.Preferably specify at this: opening and the second clip end are configured with profile complimentary to one another as follows, make the second clip end shape in locking manner and can not be fixed on the relative rotation in described opening.In this case, for example, utilize a pad that the second clip end is fixed on pin just enough, this second clip end can not pull out from be configured in the opening in the transition zone of pin like this.The second clip end after being inserted in the opening in the transition zone of pin, it can be expanded slightly equally, to so additionally produce sealed being connected of friction between the second clip end and pin.The outside second clip end that expands of opening by transition zone, then as the sealed connection of friction producing supplementary being guaranteed to the second clip end can not leave from this opening.
Specify according to another kind of embodiment: pin has U-shaped, C shape, I-shaped beam type, O shape, tubulose or oval-shaped cross-sectional configurations substantially.In the situation of U-shaped cross-section, each free end of " U " jointly formation power shift section and therefore " U " bend form pin power import section.If pin has the cross section of I-shaped beam type substantially on the other hand, power imports the surperficial edge of a wing that section has at least local buckling by one of them of i beam and forms so, and power shifts section and is made up of other, the slight curving or unbending edge of a wing of i beam.In the situation of C shape pin cross section, power imports section and power shifts the curved section formation of section by the diametrically contraposition each other of " C ", can scabble but one of these curved section shift section as power.
In order to be provided for that G shape hook is inserted into the insertion servicing unit in the through hole that is suitable for G shape hook to insert of respective holder, specify according to another kind of embodiment: pin towards at least local wedge-like of direction of its first end freely stretching out be tapered.
Preferably in this regulation: the pin of wedge-like own has two platform area that are longitudinally spaced apart from each other along pin, and in the region of these platform area, pin is not tapered.In this embodiment, pin is observed by the first wedge-shaped segment expanding along the longitudinal from its end of freely stretching out, the first platform area joining with this first wedge-shaped segment, second wedge-shaped segment of joining with this first platform area, expand and the second platform area formation of joining with this second wedge-shaped segment, wherein preferably the second wedge-shaped segment is separated by a step with the first platform area.At this, two platform area are spaced apart from each other with the size of diameter of the inner tube that approximates greatly corresponding construction support, and inner tube can be bearing on two platform area with the hole wall of its through hole in equipment state (Ruestzustand) like this.Because the platform area of pin downside distances of defining of having apart from pin different from wedge-shaped segment, therefore first ensure: length is being used the corresponding structure stand of being delimited according to G shape hook of the present invention in the situation that to have the length defining, how far irrelevant this length is pushed in the through hole of support as the pin of wedge-like with this.Secondly, guarantee by platform area: the tapered pin in wedge-like ground own can not vibrate and get loose under the dynamic load that may be applied on support.
In addition, be proved to be in the following areas useful according to the wedge-like structure of pin of the present invention, that is, can realize thus the so-called fast-descending (Schnellabsenkung) of bracket head, to realize like this Reduction of Students' Study Load of support.In other words, if pin is partly released again in the equipment state of respective holder from the through hole of described support, this makes inner tube decline along with being tapered of pin so, makes in this way support Reduction of Students' Study Load and then can be removed more easily.
Owing to there being in theory following possibility during equipment process: by pin degree like this be pushed in the through hole of support,, inner tube is not bearing on two platform area in desired mode, but be only bearing in the second wedge-shaped segment of expansion, therefore according to another kind of embodiment regulation: the second wedge-shaped segment is separated by a step with the first platform area.This step is at this to a certain extent as backstop, and the inwall of this backstop and support inner tube reclines, and prevents that thus pin is so pushed in through hole to degree, that is, inner tube is only bearing in the second wedge-shaped segment of expansion.
As from can finding out form of implementation above, understanding of the present invention is: traditional G shape is hooked in all situations and is determined greatly size by local mistake, so propose according to the present invention: make G shape hook by two independent parts pins and clip, can realize thus: only pin is configured to completely targetedly to extraordinary section bar, to can realize so the necessary moment of resistance or observe the hole wall stress allowing.But in order in fact to observe the hole wall stress allowing, the regulation according to the present invention in addition: the through hole of inner tube at least has the profile with the envelope complementation of pin along hole wall region, power is delivered to the power importing section of pin from inner tube via described hole wall region, and wherein the through hole of inner tube has different height dimensions in the tapered situation in pin wedge-like ground.If pin for example has the cross-sectional geometry of C shape, regulation so: the through hole of inner tube be similar to pin C moulding envelope and there is oval-shaped shape, thus power can be from inner tube as far as possible large area distribute and be delivered on pin via the hole wall of corresponding through hole.
For the load importing to by this way in pin being exported to by pin in the outer tube of telescopic structure stand in desired mode, by the counter nut that addressed before by load transfer to outer tube, described counter nut two of outer tube mutually alignment, be configured to two along longitudinally movable along support via being configured in external screw thread on outer tube in the region of the through hole in the gap of support longitudinal extension.At this, counter nut has smooth end side surface, the power of the pin of G shape hook shifts section face formula and is bearing in this end side surface, in the situation that tilt in order to tumble around its longitudinal axis at pin like this, produce reset force, this reset force goes back to pin in its conventional orientation, and in this orientation, pin is placed in counter nut's smooth end side surface by entire surface with its power transfer section.Not only realize by this way anti-torsion, but also additionally realized the stress of reducing effect on counter nut, therefore can not consider counter nut's surface sclerosis.The pin that can prevent thus G shape hook is pressed in counter nut's smooth end side surface, otherwise this may with undesirable mode cause counter nut under load no longer can or very difficult get loose or no longer can be for the length of support being carried out to accurate adjustment and rotating in desired mode only.

As especially can be from knowing the thin portion " A " of the Fig. 3 shown in Fig. 4, pin 12 has the cross section of I-shaped beam type substantially in shown embodiment, wherein, top flange 16 has surface smooth, that have infinitely small curvature in heart region 19 therein, and this top flange 16 is configured with respectively a curved surface its lateral side regions 20 is interior, this surperficial curvature also can obviously be greater than the curvature in Fig. 4 illustrated embodiment, and cross section is about tangent line B-B substantial symmetry like this.Top flange 16 is by web 21 or transitional region 21 and be connected with the bottom flange 18 of the pin 12 of I-shaped beam type, and wherein, the soffit of bottom flange 18 is configured to substantially smooth and have equally thus infinitesimal curvature.
The power that the upper surface of bottom flange 18 forms pin 12 shifts section 22, and this is to make to be directed to power in pin 12 and can be evenly distributed and derive because shift section by this power.On the other hand, the power that the surface of at least local buckling of top flange 16 forms pin imports section 24, imports section power is imported in pin 12 from support by this power, wherein, can realize uniform hole wall stress distribution by bending lateral side regions 20.
Due to the structure of the cross section of I-shaped beam type substantially that has of pin 12, compare and can realize identical even improved statics cross-sectional value (Querschnittswert) with less material consumption with traditional G shape hook with circular cross section, finally can reduce thus manufacturing cost.But, particularly can reduce in the following way according to the manufacturing cost of G shape hook 10 of the present invention,, pin 12 and clip 14 are different parts, so for example clip 14 can be made up of inferior Simple round steel, and pin 12 can be made up of the higher steel with for example I-shaped beam type cross section as extraordinary section bar, as this is the situation referring to figs. 1 through in the embodiment shown in 5.In other words, can be minimized in the following way due to the two-piece construction of this G shape hook according to the cost of G shape hook 10 of the present invention,, for example pin 12 is configured with the more solid member of optimized statics cross-sectional value, and is that clip 14 can use and has standard sections less statics cross-sectional value, that solidity is lower.Therefore in following a kind of embodiment, also can realize cost advantage of the present invention, pin 12 is configured with if desired easy four angle sections of rounded edge slightly in this embodiment, to can realize hole wall stress distribution as far as possible uniformly as in the embodiment referring to figs. 1 through 5 explanations.
But manufacturing G shape hook according to the present invention by two different, independent parts 12,14 is not only to be proved to be useful because pin 12 and clip 14 can have different cross sections due to two-piece construction.Or rather, due to the two-piece construction of G shape hook 10, pin 12 and clip 14 can be made up of the steel of different materials, particularly different qualities, the steel that need be for example so only S355 by quality by pin 12 is made, clip 14 can the lower steel of using character, can again reduce thus manufacturing cost.In addition, compared with traditional G shape hook, have less cross sectional area according to the clip 14 of G shape hook 10 of the present invention, this makes the clip 14 can cold forming, and the clip of traditional G shape hook is because it is compared with large cross sectional area and in all cases must hot forming.Due to cold forming, therefore manufacturing cost can further reduce.
Produce in the following way according to another advantage of G shape hook 10 of the present invention: owing to being placed on pin 12 clip 14 as independent member, so end face on the second end 28 this pin and the opposed the second end 28 of the anterior first end freely stretching out 26 or this pin 12 40 is outwards exposed and can be used as thus shock surface, by this shock surface, pin 12 can be pushed in the through hole of structure stand.Therefore clip 14 is placed on web 21 in side direction like this, and this web interconnects with the bottom flange 18 of shifting section 22 as power import the top flange 16 of section 24 as power.The fact of stretching out from this transition zone perpendicular thus for the direction of the first end freely 30 from transition zone 21 towards this clip is extended due to clip 14, so the end face 40 on the second end 28 of pin 12 is exposed thus, pin 12 can be inserted in the through hole of support by hammer by this end face like this.Because clip 14 stretches out from transition zone 21 perpendicular, so this clip 14 is in order to rise therefrom, extend towards its first end freely 30 need only bending approximately 90 °.Compared with traditional G shape hook, bend radius can increase thus, even larger like this clip cross section also can, by cold forming bending, can remain on manufacturing cost low state in this way.
Although clip 14 can side direction be welded on web 21 in the region of the second end of pin 12 28.But, in shown embodiment, specify: in the region of the second end 28 of pin 12, in web 21, be configured with opening 34, the second end 32 of this opening storage clip 14.If from Fig. 5 and 9, the most clearly know like that, opening 34 has oval shape at this, the second end that is configured as in advance oval cross section 32 of clip 14 is through this opening, like this because opening 34 produces and can not counterrotatingly be connected with the profile complimentary to one another of the second end 32 of clip 14 between pin 12 and clip 14.
In order to prevent that clip 14 may be again by pull-out from opening 34, in referring to figs. 1 through the embodiment shown in 5, jagged 36 in the distolateral middle punching press of the second end 32 of clip 14, by this breach, the second end 32 of clip 14 expands, and clip 14 is connected anti-sliply with pin 12.Clip 14 is fixed in opening 34 by the extension part producing by breach 36 but replace, can, by clip 14 and web 21 melting welding or soldering point by point, can prevents equally that in this way clip 14 from may shift out from opening 34 equally.
Although comprise having the pin 12 of the cross section of I-shaped beam type substantially referring to figs. 1 through the G shape hook 10 shown in 5, this pin 12 also can have other shape of cross section.For example pin 12 can be to have the quadrangular cross section with seamed edge slightly rounding or that be chamfered in the mode of having set forth before.Specify according to another kind of embodiment: pin 12 has the cross section of U-shaped substantially as shown in Figure 6, wherein two of " U " free ends are scabbled respectively, so that formation power shifts section 22 jointly, shift section by this power, the power being directed in pin 12 can be exported evenly distributedly.On the other hand, the opposed surface segment of pin 12 and two free ends " U " forms with the power of curved surface and imports section 24, can realize uniform hole wall stress distribution in desired mode in this way.
According to another kind of embodiment, as shown in Figure 7, G shape hook 10 according to the present invention can have one and have the pin 12 of C shape shape of cross section substantially.Be provided with equally again the power transfer section 22 that bending power imports section 24 and scabbles here, they form in this curved section by the diametrically contraposition each other of " C ".
Be illustrated referring now to Fig. 8 to 10 pair of telescopic structure stand 100 according to the present invention, this structure stand has an outer tube 112 and an inner tube 110 that energy telescopically moves in this outer tube.According to Fig. 9, outer tube 112 is provided with external screw thread 116 (for the sake of clarity not shown in Fig. 8) on its free end, and counter nut 114 is tightened onto on this external screw thread.In addition, outer tube 112 has the through hole opposite each other 113 that two forms are microscler gap, and inner tube 110 has multiple through holes that are longitudinally spaced apart from each other along support 118 on its free end, these through holes align with the microscler through hole 113 of outer tube 112.
As especially from can knowing Fig. 9, G shape hook 10 extends through and is configured in two pipes 110,112 and the through hole 113,118 being in alignment with each other with its pin 12, wherein has the cross-sectional configurations of the I-shaped beam type of particularly setting forth with reference to Fig. 4 at the pin 12 of this G shape hook 10.Therefore be passed in pin 12 and therefrom and be passed on the outer tube 112 of support 100 by counter nut 114 by the hole wall of through hole 118 from the load of inner tube 110.For the hole wall stress of the hole wall along through hole 118 is remained on little state by the mode with desired, the through hole 118 of inner tube 110 has the profile with the envelope complementation of pin 12.The surface pressing that same counter nut 114 and the power of scabbling shift between section 22 is maintained at little state, and this should shift section owing to this power and be bearing in by entire surface in counter nut 114 smooth end side surface 115.
Because the surface pressing between counter nut 114 and power transfer section 22 is maintained at little state thus, so do not exist pin 12 to be pressed into the danger in counter nut 114, otherwise this can cause can not or can only be difficult for the length of telescopic structure stand 100 is carried out to accurate adjustment rotate counter nut 114 under load can not or can only difficulty this counter nut is got loose.In addition, the trend that the G shape shape due to it of G shape hook 10 is reversed around the longitudinal axis of pin 12 is subject to the containment of the flat configuration of the power transfer section 22 of pin 12 in the following manner,, the lateral force working in pin 12 combines and is applied on G shape hook 10 as reset force with the flat configuration of power transfer section 22, and this reset force is contained the less desirable rotation of this G shape hook.
Counter nut 114 should not being set for accurate adjustment length and therefore replacing the slot-shaped through hole 113 in outer tube 112 to arrange as in inner tube 110 in the situation of multiple through holes that are intervally installed 113, these through holes 113 and/or also have through hole 118 in inner tube 110 to have and the profile of the profile complementation of corresponding pin 12.At this, the profile of corresponding through hole 113,118 needn't be accurately identical with the profile of pin 12, as long as it prevents undesirable pin rotation.Therefore also can realize by this way anti-torsion, so in this case in order to reduce hole wall stress, if be not provided for length accurate adjustment, pin 12 may be pressed into the counter nut 114 in it, so at least can abandon power and shift the flat configuration of section 22.
Be illustrated referring now to Figure 11 and 12 pairs of another kind of embodiments according to G shape hook 10 of the present invention, this G shape hook be mainly only referring to figs. 1 through the difference of the first embodiment shown in 5: pin 12 towards at least local wedge-like of direction of its first end freely stretching out 26 be tapered.Although pin 12 can be incessantly from its second end 28 until its first end 26 be tapered continuously; But specify according to the embodiment shown in Figure 11 and 12: the pin 12 of wedge-like has two platform area that are longitudinally spaced apart from each other along pin 50,52 in its power imports section 24 substantially, and in the region of these platform area, pin 12 is not tapered.Pin 12 is longitudinally observed from its first end 26s of freely stretching out by the first wedge-shaped segment 54 of an expansion, first platform area 50 being connected with this first wedge-shaped segment thus, the second wedge-shaped segment 56 and second platform area 52 being connected with this second wedge-shaped segment that be connected with this first platform area, that expand form, wherein, in the embodiment illustrating, the second wedge-shaped segment 56 is separated by the step 58 being arranged in power importing section 24 with the first platform area 50.
